广工 c语言 经典例题（C language classic example） [exercise 5.012] please fill in the appropriate content at the program vacancy only Implementation function: enter 5 integers in turn, calculate the sum of them, and output. **********/ #include stdio.h Void, main () {int, I, sum=0, n; For (i=1; i=5; i++) {scanf (%d, n); Sum=sum+n; } Printf (sum =%d, sum); } [exercise 5.029] please fill in the appropriate content at the program vacancy only Implementation function: enter integers greater than 1 to N, in the same loop statement Calculate the sum of odd and even numbers between 1 and n. **********/ #includestdio.h Void, main () {int, odd, even, I, n; Scanf (%d, n); For (i=1, odd=0, even=0; i=n; i+=2) { Odd+=i; If (i+1=n) Even+=i+1; } Printf (sum of odd=%d, odd); / * and * / odd Printf (sum of even=%d\n, even); / * and * / even } [problem 5.030] the system gives an external integer variable n and a long integer variable f (do not need to define yourself). Write procedures for the factorial n n, and will The result is stored in F. For example, when n=6, f=6... =1*2*... *6=720. Note: 0! =1. **********/ Void, main () { Int a=1; F=1; If (n==0) f=1; Do { F=f*a; A+=1; } While (a=n); } [problem 5.032] the system gives an external integer variable n and a long integer variable f (no) Need to be defined by itself. Write procedures for the N double factorial n!! And bring the result Store to F. The double factorial definition is: When n is odd, n! Product of all odd numbers not greater than n, Such as: 7!! =1 * 3 * 5 * 7. When n is even, the product of all even numbers not greater than n (except 0), Such as: 8!! =2 * 4 * 6 * 8. **********/ Void, main () { Int a; F=1; If (n==0) f=1; Else if (n%2==0) a=2; Else a=1; Do { F=f*a; A+=2; } While (a=n); } [problem 5.034] the system gives an external integer variable n and a floating point variable Quantity f (do not need to define by yourself). Write programs to find negative integer n The factorial n, and stores the results in F. Assume that M is
